Title:
COLLECTING METHOD FOR EXHAUST HEAT
Document Type and Number:
Japanese Patent JPS5726393
Kind Code:
A
Abstract:
PURPOSE: To improve a heat collecting factor, by a method wherein recuperators for combustion air and for combustion gas are aligned in parallel in a smoke flue in a gas heating furnace, and distribution of exhaust gas to each recuperator is equalized to its heat capacity specific ratio.
CONSTITUTION: Recuperators 3, 3 for combustion air and for combustion gas are aligned in parallel in an exhaust gas flue 2 in a heating furface 1, and exhaust gas distributed to each of the recuperators 3, 3 so as to become approximately equal to its heat capacity ratio. In case air and gas for combution are preheated by exhaust gas, this enables the wide improvement of a heat collecting factor and permits operation of the furnace at the best condition.
